To aZZ whom it may" concern.- Be'it knownthatL'Arinxtnnnnfionpori;

of/ Rochester, in thefcounty of Monroe and State of New York,--hav'einvented e'ertainnew and useful Improvements inGrain-Separators;

andl-do herebydeclare thefollowing to be a' full, clear, and exactdescription oi the same, reference being-had to the accompanying draw=ings, making a part of this specificatiom'in I. I i.

Figure 1 represents a perspective View; of grain t-hrasher, separator,and couveycrco'm- "plete; and Fig. 2 represents a longitudinal verticali section throngh thesam'e.

' Similar letters of reference where they'occur -in the separate figuresdenote like paths of themachine in both.

In grain thrashi ng'and "separating machines a shake-motion has beengiven to the straw belt or raddie; but though this shake-motion v is valnable'in shaking out considerable grain that might otherwise be carriedout with the straw and lost, yet italso shakes th rough straw and otherstufi which get into the fan-case and on the sieves, and prevent thefree action of the machine.

The object of-jmy invention is -to retain the advantages of theshake-motion to the raddle and to'obviate the disadvantages arisingfromv it-vi'z., the clogging of the fan or of thesieves by the straw,which by the ordinary construc--' tion ofseparators also passed'thronghthe. rad-f die; and thenat-ureof my invention consists,

in combining witha straw belt or raddleha'v iing a shake-motiomh rack orseries gfsiats placed within the belt or raddlefo'n the pol 'pose ofpreventing"the-straw"-from falling through the ,belt and thence passinginto the 3 machine.
